i think i found a fix. i was also getting this Black Ops 2 not responding thing as well. i would load up the game, through steam, and it would just sit at a black screen. i would then have to ctrl alt del and end process. anyway, what i did was i went to my Steam Library, and right clicked on Call of Duty: Black Ops 2. in the General tab, i clicked on the button Set Launch Options. once there, i typed in -dontForceMinReqs and then pressed Ok. after that, i tried relaunching BO2 and guess what, it worked! idk if this will solve it, but it did for me, so you should try it as well if you haven't found a way. best of luck!
